Accupro 6/431090 Square End Mill 3/32 in 3 Flute Carbide

Product Description

The ACCUPRO 6/431090 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 3/32 inch (0.0938 inch) cutting diameter and three spiral flutes at a 30-degree helix angle, it delivers clean, efficient material removal in a compact form factor. The uncoated micrograin carbide construction provides rigidity and edge retention in a regular-length profile. At 1-1/2 inches overall length with a 9/32 inch length of cut, this end mill is suited for tight-tolerance work in confined areas. Machinists and CNC operators working in job shop or production environments install this tool in standard milling machines and machining centers.

This end mill is built for right-hand cut and right-hand flute operation, making it compatible with conventional spindle configurations. The centercutting design allows plunge milling in addition to peripheral and slot milling. The 1/8 inch shank diameter fits standard collets and tool holders commonly used on benchtop mills, mini mills, and full-size vertical machining centers handling small-diameter work. It is well suited to slotting, profiling, and contouring in aluminum, brass, steel, and similar machinable materials where a small-diameter, rigid carbide tool is required.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• 3-flute spiral design at 30-degree helix angle for efficient chip evacuation
• Centercutting capable — supports plunge, slot, and profile milling
• Right-hand cut and right-hand flute for standard spindle compatibility
• Uncoated finish suitable for a broad range of machinable materials
• Mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance work

Compatibility

Designed as an OEM-style replacement or direct-use tool for standard 1/8 inch collet and tool holder systems used in CNC machining centers and manual milling machines running small-diameter end mill operations.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling practices. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully in the collet to the recommended engagement depth and torque the collet nut per the tool holder manufacturer specifications. Verify runout with a dial indicator before cutting to protect both the tool and the workpiece.
